I am currently running my 2w beacon with the following sequential multi-tone Hellschrieber ID on 30m:

As Colin, G6AVK pointed out, this is likely to be a lot less effective than my previous MV identifier, but if it does work, people might have a better chance of knowing who the beacon actually is. I’ll let it run for a while and see how it does. Propagation is falling off a bit for me now, but might get better later.
